In 'Growing in Christ,' J I Packer offers readers an easy-to-follow road map for studying theological topics, including the Apostles’ Creed, the Lord’s Prayer, the Ten Commandments, and baptism. Each chapter helps both new and lifelong believers examine what Packer calls “the intellectual ABCs” of the gospel so they can grow in faith. J I Packer outlines the differences between faith and belief to help you grow in Christ. While "belief" suggests bare opinion, "faith," whether in a car, a patent medicine, a protégé, a doctor, or a marriage partner, is a matter of treating the person or thing as trustworthy and committing yourself accordingly. The same is true of faith in God, and in a more far-reaching way.
